the router does not really care which OS you run on your computer. Most manufacturer don't expect people to still use Win2k since there is no more support for this OS.
the default IP for the Linksys network is 192.168.1.0
is you printer on the 192.168.33.0 network? If so assign a static ip of the 192.168.33.0 scheme to on of the computers, log into the printer, and change its ip to match the 192.168.1.0 scheme, finally set the computer back to DHCP.
the other option is to set the Linksys LAN IP to 192.168.33.1
